Abstract

An edger/trimmer of two-piece construction having a foam painting pad secured to a large outer face of an L-shaped frame from the back of which extends a handle plate. The short section of the L-shaped frame serves as the guide, which contacts the abutting surface and provides smooth, straight movement of the pad along the surface to be painted. The pad and guide are uniquely designed and configured so that nearly all facets of edging and trimming can be easily, quickly and accurately accomplished.

RELATED APPLICATIONS

Applicant claims the benefit of provisional application Ser. No. 61,007,799, filed Dec. 17, 2007.

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to paint application implements, and in particular, the present invention relates to pad type implements used to apply paint to the edges around ceilings, doors, windows, and trim, and also to the trim pieces themselves.
2. Description of the Prior Art
While the majority of wall painting is done with rollers, the edging and trimming has always remained a difficult task. As an alternative to using a brush, which normally requires a high level of skill, a myriad of edging and trimming pads has been developed. However, as with a brush, difficulty still remains when attempting to paint straight lines along the edges of a wall or ceiling, around door and window trim, or to accurately paint the trim and molding pieces themselves. In order to achieve a neat, acceptable appearance, the lines must be straight and the painting must be done without contacting the adjacent walls or trim. Also, the painting must be done without flooding the corners with excess paint, which results in a sloppy finish.
One major drawback to most common edger and trimmer pads is in the design of the standoff guides upon which they rely. Some of the pads employ integral rollers, which contact the abutting surface. These roller systems are generally complicated and expensive to manufacture. They are also easily fouled with paint and are difficult to clean.
Other pads employ planar or angular movable guide plates, which are intended to abut the adjacent surface and are pulled away when the pad in dipped into the paint. These movable plates are generally expensive to manufacture, difficult to use and are too easily fouled with paint.
Still other pads employ fixed, planar guide plates which also serve as the pad attachment frame. These generally provide only a very thin contacting edge with the abutting surface, which tends to be unreliable in that the pad can easily tilt, resulting in an uneven application of paint. These pads also perform poorly when used on trim and molding. In addition, these pads do not account for paint buildup along the edge of the pad which will constantly foul the contacting edge of the guide.
Many other painting pads have no guide at all and would require an extremely high level of skill if used for close edging or for painting molding. These pads are generally useful only for rough work.
Another major drawback to most common edger and trimmer pads is the type and orientation of the absorbent pad itself. The short, flexible bristle pads which most of the edgers employ have a built-in flaw, which is the unpredictable position of these bristles due to their natural flexing action. This often results in crooked lines in addition to likely flooding of the corners. One edger employs a foam pad and has a planar guide which is very thin and will easily be fouled with paint. This edger is not useful on molding and makes no accommodation for painting into corners, although this seems to be the main claim of this edger.

DETAILED DESCRIPTION OF THE INVENTION

FIGS. 1 and 2 are side and back views of paint edger/trimmer 10 which comprises a one-piece, L-shaped, molded plastic frame 12 whose larger section is backing plate 14 to which pad 20 is securely attached to outer face 36. The smaller section of the frame is guide plate 16, which extends at a 90 degree angle from backing plate 14 and serves as a guide which contacts and slides along the adjacent surface (wall, trim or glass), which is not to be painted.
Left and right ends of guide plate 16 are arcuate 40 to provide ease of movement across the unpainted adjacent surface. Handle plate 18 is integrally molded into the frame 12 of edger 10 and extends at a 90 degree angle along the centers measured from left to right of the inside edges of both plates 14 and 16. A handle plate 18 provides the gripping surface for the edger and also serves to stabilize plates 14 and 16 so that a 90 degree position between these two plates is maintained. FIG. 3 illustrates a second embodiment of the handle plate 18 which comprises two spaced apart handle plates which allow for more comfortable gripping of the edger.
Painting pad 20 is made of polyurethane foam and is attached at its back, inside surface 33 by means of a securing means such as glue or the like to outer face 36 of backing plate 14. Pad 20 is approximately 5/16 inch thick from inside surface 33 to outside surface 34.
Pad 20 is square or slightly rectangular in nature and extends vertically from its bottom 32 at the bottom 38 of plate 14 to the bottom of triangular ridge 22. The two projecting sides of triangular ridge 22 are approximately 1/32 inch long. Ridge 22 extends the entire width of the outer face 36 of plate 14 and is located approximately ⅛ inch below the plane of the top of plate 16. The top side of ridge 22 projects at a 90 degree angle from plate 14. The bottom of ridge 22 projects at an approximately 30 degree angle downward from the top side of ridge 22 and terminates approximately 3/16 inch below the plane of the top of plate 16. The bottom, angled side of ridge 22 provides a guide for precise positioning pad 20 when it is secured to plate 14.
The top of pad 20 has an approximately 30 degree bevel 24 extending from outer plane 26 to inner plane 28. The juncture between plates 14 and 16 has curved area 30 which, along with bevel 24, produces a void which allows excess paint to collect and be reabsorbed into pad 20. This void performs the vital function of keeping paint from contacting the adjacent surface and from fouling the outer/contacting surface of plate 16.
While the entire outer surface 34 of pad 20 is used to apply paint, the uppermost corner 50 which extends between left corner 26 and right corners 52, produces the close straight lines, i.e. edging or “cutting in” as it is called in the trade. The top of edge 50 terminates in height 1/32 inch below the plane of the top of plate 16. This 1/32 inch clearance keeps paint from flooding the corners between adjacent walls or between trim pieces and abutting surfaces. This clearance also reduces the chance that the pad and paint will contact adjacent surfaces which are not to be painted.
Due to excess pressure by the user, paint may accumulate along ridge 22 and curved area 30. This accumulation does not affect the overall performance of the edger and any paint which is not reabsorbed back into the pad can be periodically wiped away. This achieves the important result of keeping the straight/contacting area of plate 16 from becoming fouled with paint.
Pad 20 extends beyond the edges 46 of plate 14, forming overlaps 44, which extend approximately ⅛ inch to the left and right of the edges 46 of plate 14. Overlaps 18, and in particular the extreme ends of pad 20 at left and right sides 48, left and right corners 42, and left and right corners 26 and 52, allow for painting fully into corners where two adjacent walls meet, especially at ceiling junctures, and for painting into corners where mullions or other trim or molding pieces meet at 90 degree or similar angles. Without this overlap feature, a separate fine brush would be needed to paint such corners.
FIG. 4 is a view of the corner where two walls 54 and 56 meet at a juncture with ceiling 58. Edger 10 is positioned along wall 54 with plate 16 abutting ceiling 58 and is shown applying paint to wall 54 as depicted by shaded area 60. The application of paint fully into corner 62 is depicted by shaded area 64 on wall 56 which is accomplished due to overlap 44 of pad 20.
FIG. 5 is a view of mullions 66 and 68 constructed around the perimeter of window glass 70. Edger 10 is positioned along mullion 66 with plate 16 abutting glass 70 and is shown applying paint to mullion 66 as depicted by shaded area 72. The application of paint fully into corner 74 is depicted by shaded area 76.
Therefore, while the present invention has been disclosed with respect to the preferred embodiments thereof, it will be recognized by those of ordinary skill in the art that various changes and modifications can be made without departing from the spirit and scope of the invention. It is therefore manifestly intended that the invention be limited only by the claims and the equivalence thereof.
